However, the practice of jailbreaking has some legal support from the United States Copyright Office.
Jailbroken iPhones Have Stability Issues
Since jailbroken app developers don't have to follow memory and CPU usage guidelines set by Apple, the result might be reduced battery life, slower performance relative to non-jailbroken iPhones, and possible random reboots.

Performance management apps are available for jailbroken iPhones, but you may have to configure different settings if the phone has problems or issues.
Warranty Is Void If You Send Your Jailbroken iPhone for Service
Apple doesn't provide support for jailbroken iPhones. If Apple finds out that you went through that process, it won't honor your warranty, and it may not matter if the issue you're requesting service for isn't related to the firmware.

If you're willing to wait, your favorite jailbreak-only iPhone feature may make its way to a new version of iOS sooner or later. If a must-have feature arrives that you don't think will make it into a new version of the iPhone iOS, then jailbreaking may be the only way to get it.

You Could Brick Your iPhone
Bricking occurs when you do something to the phone that leaves it in an unusable state that can't be fixed by rebooting or reloading the software. While irreversible bricking of an iPhone is rare, it's always a risk when attempting a jailbreak, especially if the software is in beta form and hasn't been through a lot of testing.You May Get Locked Out of the App Store or Other Content Services
Although Apple doesn't appear to be taking major actions against jailbreakers, it could happen in the future, as Sony has reportedly done with people who hacked PS3s by locking jailbroken PS3 users out of the PlayStation Network and its services.

Others may follow suit, making jailbreaking less appealing to people who view media on mobile devices.
Jailbreaking Can Open Up Your iPhone to Malware
The Apple security team doesn't play a role in reviewing the code of non-iTunes App Store software, so you must rely on developers to police their code for potential security vulnerabilities. Malware developers may also create iPhone-specific viruses, spyware, and other malware disguised as legitimate apps.

If you do jailbreak your iPhone, change the root password as soon as the jailbreak is complete, or you may become the victim of a hack. It's your decision whether the potential hazards are worth the perceived benefits of jailbreaking. For many jailbreakers, it's not about the cool apps; it's about the freedom to put whatever they want on a phone without restrictions. However, that flexibility may introduce complications that aren't worth the risk.
